Application filed December 19, 1917.

To all whom it may concern Be it known that I, Trrnooonn F. P111- LIrrI,a citizen of the United States 'of America, a residentof East St. Louis,in the county of St. Clair, State of Illinois, have invented certain newand. useful Int provements in Crushers, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming a part of this specification.

My invention relates to improvements in Crushers, the object being toprovide a simple and very efficient means for crushing, or crushing andpulverizing, various kinds of material, such for example as marblechips. The preferred form of the invention comprises a rotatablecrushing device arranged withim a rotatable annular-housing. Thematerial to be crushed and pulverized is introduced through acentral intake opening in the rotatable housing, and the pulverized product isdrawn out, by suction, through a central cischarge opening. The noveltylies in certain combinations of elements and certain details ofconstruction which will be hereinafter described and set forth in theclaim.

Figure I is a side elevation of a crusher and pulverizer constructed inaccordance with mv invention. j

Fig. TI is a vertical section.

Fig. III is a section taken on the line TIL-HI, Fig. 11.

The structure herein shown comprises bearings 1, ahorizontal shaft 2rotatably mounted in said bearings, a drive pulley 3 fixed to said.shaft, a crushing device comprising a spider 1 secured to the shaft 2,pins or lingers 5 extending laterally from the arms of the spider 4t,and crushing rings 6 loosely mounted on said pins 5. These pins areconnected together and reinforced by a retaining ring 7 (Figs. I andIf), the extended end portions of said pins being re duced and providedwith screw threads. Nuts 8 are fitted to the threaded ends of pins 5 tosecure the retaining ring '7. The relatively small crushing rings 6 areloosely mounted between the spider 4 and the retaining ring '7.

The crushing elements ust described are surrounded by a rotatableannular housing A, mounted in a stat onary circular support 9, providedwith bearings 10 for antifriction rollers 12 which engage the pe-Specification of Letters Patent.

ripheral face of said rotatable housing, the latter having guide flanges13 at opposite sides of the rollers. The anti-friction rollers 12 allowthe annular housing to turn freely around the internal crushingelements, and'the guide flanges 13 cooperate with the rollers to securethe housing to the stationary supporting ring 9. A large crushing ring14, carried by the housing, cooperates with the relatively smallcrushing rollers 6 to pulverize the material in the housing. This largecrushing ring 1st is made of a number of arcuate sections 1% (Fig Ill.)secured to the peripheral wall of the housing by means of radial screws15, the heads of the screws being eX- posed at the periphery of thehousing, and the arcuate sections 1-1 being threaded to receive thescrews. These arcuate sections as well as the small crushing rings 6,are preferably made of hardened metal.

The opposite side walls of the housing are preferably offset andprovided with converging annular faces 16 and 16 (Fig. ll) whereby thematerial to be crushed is directed to the segmental crushing ring 14.

One side wall of the rotatable housing is provided with a central intakeopening 17 (Fig. ii) and an approximately L-shaped stationary intaketube, or chute, 18 extends into said opening. This stationary intakemember is secured to one of the bearings 1, as shown in Fig. 11. Therotatable housing is also provided with a central discharge opening, andan approximately Lshaped suction tube 19 (Fig. 11) extends into thisopening. The pulverized material can be drawn through the suction tube19 by means of a suction fan, as indicated in Fig. II. This suction tube19 is stationary and it may be provided with a bracket 20 secured to oneof the bearings 1.

The power transmission devices include the shaft 2 which extends throughthe suction tube 19 and also through the central openings in therotatable housing, a sprocket wheel 21 secured to said shaft, :1 chainwhereby power is transmitted from said sprocket wheel to a largersprocket 23 on a shaft 24:, a pinion25 se cured to said shaft 2%, and alarge gear ring 26 meshing with said pinion. The large gear ring issecured to one side of the rotatable annular housing. The internalcrushing elements revolve at a relatively high speed, while the annularhousing turns 10 mounted on the reduced ends of said. Bins.

securing means on said reduced ends, said retaining ring being confinedbetween the said shouide and said securing means and crushing meansloosely mounted upon the said pins between the i'etatable carrier andthe retaining ring.

In testimony that I (him the foregoing I. hereunto aflix. my signature.
